Force meter

We put the statuette on the force meter, which showed a value of 25 N. Then, we placed it on the force meter, completely immersed in the water. The force meter showed a value of 17 N. What is the statuette's volume?

Correct answer:

V =  0.8 l

Step-by-step explanation:

$$\begin{gathered} F_1=25\text{N} \\ {F}_2=17\text{N} \\ g=10{\text{m/s}}^2 \\ \rho =1\text{kg/l} \\ {F}_2=F_1-mg \\ {F}_2=F_1-V\rho g \\ V=(F_1-F_2)/(\rho \cdot g)=(25-17)/(1\cdot 10)=0.8\text{l} \end{gathered}$$
